Stellar Pharmaceuticals Receives 2nd Uracyst® Patent in United States of America

LONDON, ONTARIO--(Marketwire - Jan. 26, 2012) - Stellar Pharmaceuticals Inc. (OTCQB:SLXCF)(OTCBB:SLXCF)(PINKSHEETS:SLXCF) ("Stellar" or "the Company"), today announced that it has received another patent from the U.S. Patent and Trademark Office (USPTO) for intellectual property central to one of the Company's lead products, Uracyst® (a sterile sodium chondroitin sulfate solution, 2%), which is used in the treatment of interstitial cystitis/painful bladder syndrome ("IC/PBS").

Stellar's second patent issued as United States Patent No. 8,084,441, entitled "Cystitis Treatment with High Dose Chondroitin Sulfate," relates to the treatment of IC/PBS by instillation of an optimized unit dose of chondroitin sulfate that is at least 350mgs or more. The Company expects this patent to issue. Once issued, the patent will expire in 2023.

Rob Harris, Stellar's President and Chief Executive Officer, commented, "This second patent expands the scope of Stellar's exclusive rights in the United States for Uracyst, and further validates the innovative nature of Stellar's approach to the treatment of interstitial cystitis/painful bladder syndrome, and underscores the Company's position as a leader in this field. Mr. Harris went on to say that several companies have expressed an interest in the US rights to Uracyst."

About Uracyst®

According to published literature, up to 70% of IC patients have defects in their bladder glycosaminoglycan layers. The glycosaminoglycan ("GAG") layer is a mucosal lining of the bladder that acts as a protective barrier against irritants and toxins in the urine and defends against bacterial adherence. When the GAG layer is damaged, these irritants and toxins in the urine seep through, causing an irritation to the bladder wall. This results in increased frequency and urgency to void (up to 60 times a day). Many IC/PBS patients also experience severe pelvic pain. These symptoms can be debilitating and have a serious impact on a patient's quality of life.

The instillation of chondroitin sulfate (ChS), one of the main components of the GAG layer that is reduced in IC, restores the barrier function. Uracyst® 2% 400 mg was developed to specifically replenish this GAG defect in IC/PBS patients.

Uracyst® 2% (400 mg) ChS dose has been shown to be the ideal dosage to saturate the bladder, thus restoring the barrier function. Instilled fluid volume of 20 mL Uracyst® (400mg) also allows patients to retain the treatment in the bladder for a longer period of time, enabling a better uptake of the delivered dosage and a faster onset of symptomatic relief. Uracyst® is also one of the most cost effective treatments for these patients. Combine treatment efficacy with the most cost effective therapy and it becomes understandable why Uracyst® is becoming the product of choice in treating IC/PBS. Uracyst is sold in Canada, Europe and parts of Asia but has not been approved for marketing in the US.
